A2AShield: TLS Mutuo Post-Quantistico, Attestazione DID W3C e Delega Crittografica

A2AShield fornisce fabric di comunicazione crittografica zero-trust, TLS reciproco post-quantistico (mTLS) e catene di delega verificabili per agenti IA autonomi, consentendo a sciami multi-agente di negoziare, effettuare transazioni ed eseguire flussi complessi senza rischi di impersonificazione o intercettazione quantistica.

Architectural Layers & Protocols

Agent Cryptographic Identity Plane (Decentralized Identifiers (DID) / SPIFFE for Agents): Assigning each autonomous AI agent a unique, non-spoofable post-quantum cryptographic identity.
Mutual Post-Quantum Transport (Mutual TLS 1.3 with Hybrid ML-KEM/ML-DSA): Encrypting and mutually authenticating all inter-agent messages, prompts, and tool results.
Cryptographic Delegation Chains (Macaroons / Biscuits with Post-Quantum Signatures): Encoding precise task delegation, spending allowances, and operational scopes from human to agent.
Anti-Prompt-Injection Boundary (Structured Content Enclaves & Attested Tools): Isolating untrusted user inputs from high-privilege agent execution tools via cryptographic gates.

Key Metrics: < 3 ms (Agent-to-Agent Handshake) | 100% (Delegation Chain Verification) | Zero-Trust (Mutual Authentication Standard) | Immutable (Reasoning & Action Audit Logs)
